AUTOMOBILE-RADIATOR.

Application filed April 12, 1919.

T 0 all whom it may concern.

Be it known that I, ABRAHAM GnnsHKorF, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Automobile- Radiators, of which the following is a specification.

This invention relates to certain new and useful improvements in an automobile radiator and more particularly to the formation and construction of the radiating surface and cellular portion thereof.

The principal object is to provide a strong cellular unit in which the component parts or sections are united by means of solder, or the like, and which uniting material enters into the structural make-up for reinforcing the joints between sections.

Further, the invention resides in the salient features of construction and the com- )ination and arrangement of complemental sections, hereinafter described in detail, claimed in a succinct manner, and illustrated in the attached drawing wherein- Figure 1 is a front elevation of a fragmentary portion of a radiator embodying the present invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a vertical transverse section therethrough on line 33 of Fig. 2, and

Figs. i and 5 are horizontal cross sectional views through Fig. 1 on lines 14 and 55, respectively.

Proceeding in accordance with the invenion, the radiating surface of the radiator s made up of an alternate arrangement of we sections 1 and 2, each formed from a single strip-like sheet of metal which is stamped into proper shape and bent centrally to define horizontal air passages and soldered along their free edges or ends, as indicated at 3. To this end, the strips are stamped and shaped so thatwhen they are bent along a central line, the arms or sides of the U-sheet are contracted at intervals into contacting relation, as indicated at 4:, whereby a vertical series of horizontal air passages 5 is provided, those of section 2 being smaller in cross sectional area than those of section 1 and have attenuated upper and lower extensions as defined by the parallel portions 6 of the sheet, said extensions projecting between the comparatively large air passages of section 1 as is clearly depicted in Fig. 3.

Specification of Letters Patent.

Serial No. 2891588.

This arrangement of the sections 1 and 2 provides zig-zag vertical water passages 7 therebetween, the narrowest portions of the water passages occurring opposite and between the larger air passages whereby an efficient cooling will be expeditiously effected. It is to be further noted that the sec tions 1 have their soldered ends 3 located at the bottom of the radiating surface and the sections 2 have their ends 3 disposed at the top or upper side of the surface thereby equally distributing the soldered joints on opposite sides of the surface for further strengthening the structure.

()ne series of sections, preferably sections 2, has its vertical edges flared or beveled outwardly into contact with the correspondin edges of adjacent sections 1, as indicated at S, such spreading flare vof the section edges occurring at the opposite ends of the smaller air passages and opposite the widest portions of the vertical water passages.

In assembling the parts of a radiator, the sections are alternately arranged within a suitable form and the contacting edges 9 and 10 are then dipped in solder for securing the parts rigidly together. By this step of dipping, solder is permitted to flow in between the parts or sections approximately to the planes AA, B-B, whereby a wedge of solder will be formed on the interior of the water passages. This wedge of solder occurs at the widest portion of the water passage and greatly strengthens the same as well as prevents leakage.

The construction is easily and quickly assembled by the alternate arrangement of the sections; the flaring of the opposite ends of the smaller air passages does not materially weaken but rather strengthens the same; and the wedge of solder affords a simple, expeditious method and means for greatly reinforcing the structure without special uniting operations and machinery. The flared ends of the air passages occur at vertically spaced points whereby the wedges will also be arranged in vertical series, the intervening edge portions being offset in parallel and contacting relation to afford comparatively wide contacting surfaces 11, as depicted in Fig. 5.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. A radiator comprising two series of sections arranged in alternation, each section stamped and shaped from a single strip-like sheet of metal bent upon a central 7 line to provide a vertical series of horizontal with the edges of adjacent sections, and soli of the adjacent sections and disposed rear-. wardly of the said contacting edges'of the der joining the edges of adjacent sections and forming continuous wedge reinforcements between the opposite edges of the smaller air passages and the edge portions sections. I

2. A radiator comprising two series of sections arranged alternately and contacting along their edges to define intermediate water passages, each section formed to provide a'vertical series of horizontal air passages, the opposite ends of the air passages of one series being flared outwardly along the vertical side edges thereof whereby when the contacting edges are "dipped in solder the latter will flow into the wedge-shaped crevices formed by the flared edges and provide continuous wedge-shaped reinforcements disposed rearwardly of the said contacting edges of the sections.

A radiator comprising a plurality of sections each including a vertical series of horizontal air passages, said sections arranged side by side and defining intermediate vertical water passages, the opposite ends of certain air passages being flared along the vertical edges thereof toward the adjacent edges of adjoining sections, and a continuous body of solder joining the sections and filling the spaces defined by the flared edges and the adjacent edges to provide added reinforcement thereat which reinforcements are located rearwardly of the said edges.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
